Gas chromatography-mass spectrometry (GC-MS) identified key volatile compounds within these oils. In vitro anti-fungal assays evaluated their efficacy individually and in combinations using checkerboard dilution techniques to assess synergy. Results indicated significant antifungal activity, with lemongrass exhibiting the strongest effect (MIC of 0.125% v\/v). Notably, a 1:1 combination of lemongrass and kaffir lime essential oils showed synergism, reducing the MIC to 0.0625% v\/v. The antifungal activity was primarily attributed to citral and citronellal, with MICs of 0.03125% v\/v and 0.125% v\/v, respectively. Molecular orbital analysis revealed that the higher energy levels of the lowest unoccupied molecular orbitals (LUMOs) in citral correlate with greater antifungal efficacy, likely due to its enhanced electrophilicity, facilitating nucleophilic interactions with M. furfur\u2019s cellular components. These findings highlight potential applications of essential oil combinations in antifungal therapies.<\/jats:p>","DOI":"10.3390\/ijms26125601","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T11:18:40Z","timestamp":1749640720000},"page":"5601","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Synergistic Antifungal Properties, Chemical Composition, and Frontier Molecular Orbital Analysis of Essential Oils from Lemongrass, Kaffir Lime, Lime, Dill, and Shatavari Against Malassezia furfur"],"prefix":"10.3390","volume":"26","author":[{"given":"Sarin","family":"Tadtong","sequence":"first","affiliation":[{"name":"Department of Pharmacognosy, Faculty of Pharmacy, Srinakharinwirot University, Nakhonnayok 26120, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rada","family":"Chantavacharakorn","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmacy, Srinakharinwirot University, Nakhonnayok 26120, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarocha","family":"Khayankan","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmacy, Srinakharinwirot University, Nakhonnayok 26120, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Puriputt","family":"Akachaipaibul","sequence":"additional","affiliation":[{"name":"Department of Pharmacognosy, Faculty of Pharmacy, Srinakharinwirot University, Nakhonnayok 26120, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanna","family":"Eiamart","sequence":"additional","affiliation":[{"name":"Chula Pharmacokinetic Research Center, Faculty of Medicine, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9301-5038","authenticated-orcid":false,"given":"Weerasak","family":"Samee","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Chemistry, Faculty of Pharmacy, Srinakharinwirot University, Nakhonnayok 26120, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"130","DOI":"10.4103\/0019-5154.62734","article-title":"Dandruff: The most commercially exploited skin disease","volume":"55","author":"Ranganathan","year":"2010","journal-title":"Indian J.
